CPT® Code 93566

Add-On Code

Injection procedure during cardiac catheterization including imaging supervision, interpretation, and report; for selective right ventricular or right atrial angiography (List separately in addition to code for primary procedure)

The CPT® Code 93566 refers to an injection procedure performed during cardiac catheterization specifically for selective right ventricular or right atrial angiography. This procedure is integral to the assessment of the right side of the heart, allowing for detailed visualization of the right ventricle and right atrium. During this procedure, a catheter is carefully positioned within the right heart chambers, and contrast media is injected to enhance the imaging quality. The resulting angiograms, which are the images produced from this process, provide critical information regarding the anatomy and function of the right heart structures. Following the injection, the physician reviews the angiograms and generates a written report that interprets the findings. It is important to note that this code is used in conjunction with a primary cardiac catheterization code, as it is considered a separate and additional procedure that contributes to the overall evaluation of the patient's cardiac condition.
